| Abstract | Beetle diversity and species composition were studied using pitfall traps placed along three parallel transects that extended from the center of a downhill ski trail, 100 m into a large, unfragmented spruce-fir forest on Mount Mansfield State Park, VT, USA. Groups of beetles showed associations with three distinct habitats: ski trail openings (Agonum cupripenne, Amara spp., Poecilus lucublandus, Hypnoidus bicolor, and H. abbreviatus), edge (Pterostichus coracinus, Agonum retractum, Sphaeroderus canadensis, and Calathus ingratus), and forest (Pterostichus adstrictus, P. punctatissimus, P. brevicornis, Platynus decentis, Trechas apicalis, T. crassiscapus, and Eanus maculipennis). Consequently, carabid and elaterid species composition in the ski trail, edge, and 5 m into the unfragmented forest showed nearly complete turnover. Most beetles within the ski trail were colonizers from lower elevations; however, one species, H. bicolor, was a tundra species that appeared to have colonized lower elevations along the ski trail opening. Of "forest" beetles, only 2 of 540 individuals (< 0.5%) were collected in the ski trail opening. Thus, ski trails are strong barriers to dispersal for forest beetles, several of which are flightless or dimorphic and primarily short-winged. Consequently, fragmentation of mountain slopes by ski trails, especially those that run perpendicular to the climatic gradient, may put isolated populations at a greater risk of local extirpation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
